You have a Microsoft Teams Phone deployment. The 613 7010 5XXX phone number range is allocated to the Session Border Controller (SBC). A user named User1 is configured as shown in the following exhibit. User1 reports that when an external caller attempts to call the phone number of User1, the external caller receives an error message. User1 can make outbound calls, but no caller ID appears. Which two commands should you run to resolve the issues? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

Accepted Answer

A. Grant-CsCallingLineIdentity -Identity user1@litwareinc.com -PolicyName CallerID Grant-CsCallingLineIdentity assigns the CallerID policy to User1, which defines what phone number or identity is presented to recipients during outbound calls, directly resolving the missing caller ID symptom. Without this policy assignment, Teams has no configured caller ID to present on outbound calls. This is the correct fix for the outbound caller ID issue. D. Set-CsPhoneNumberAssignment -Identity user1@litwareinc.com -PhoneNumber +61370105555 Set-CsPhoneNumberAssignment with -PhoneNumber +61370105555 assigns a Direct Routing number from the SBC's allocated 613 7010 5XXX range to User1, enabling the PSTN to route inbound calls correctly to the user's Teams client. Without a phone number assignment, inbound calls have no destination in Teams, causing the error the external caller receives.

Answer

B. Grant-CsOnlineVoiceRoutingPolicy -Identity user1@litwareinc.com -PolicyName $null Setting the OnlineVoiceRoutingPolicy to $null removes the voice routing policy from User1 entirely, which would disable outbound PSTN calling rather than fix any reported issue.

Answer

C. Remove-CsPhoneNumberAssignment -Identity user1@litwareinc.com -PhoneNumber Remove-CsPhoneNumberAssignment removes an existing number assignment rather than adding one, which would worsen the inbound routing failure instead of resolving it.

Answer

E. Set-CsPhoneNumberAssignment -Identity user1@litwareinc.com -EnterpriseVoiceEnabled $true Since User1 can already make outbound calls, Enterprise Voice is already enabled, so setting EnterpriseVoiceEnabled to $true on the number assignment would be redundant and resolves neither the inbound error nor the missing caller ID.
